Specification of Letters Patent.

Patented a s, 1918 Application filed December 8, 1917. Serial No. 206.224.

To all whom, it may concern.-

Be it known that I, THOMAS P. MADDEN,

, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new anduseful Improvement in Locomotive Ash-Pans, of which the following is afull, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to theaccoman in drawin 's forliniii iart of this a a: z:

specification, in which,

Figure l is a sideelevational view of my improved locomotive ash pan.

Fig, 2 is an elevational view looking to-- ward the front of the locomotive.

Fig, 3 is a cross sectional view of my im-. proved ash pan.

Fig. 4: is a detail view of certain of the parts of myimproved ash pan before the same are pressed into shape.

This invention relates to a new and useful improvement in locomotive .ash pans of the type shown and disclosed in my United btates Letters Patent No. 1,107,682' dated August 18, 1914, the object of my present invention being to simplify the invention and to cheapen the cost of manufacture.

As disclosed in my aforesaid patent, the

ashes from the grate bars drop into the ash box and are then flushed out by water under pressure. These principles Iliave proposed to follow in the present instance by' providing a water head 1 in which water is supplied from the tank, preterably under pressure,-sa1d water flushing the ashes down through the trough shaped bottom member To these brackets 23 are secured the mom ner edges are provided with flanges 4 to,

which latter are securedthe wall portions 5 of the rounded trough shaped member 6 of the ash pan. This rounded trough shaped bottom member is preferably formed from a-segmental piece ofrolled sheet iron or steel, as shown in Fig. 4, and by its con? formation, when curled up, it is made deeper at one end than at the other. The deepest portion is covered by a door 7 which may be opened or closed by an operating rod 8 which maybe reciprocated by the engineer by suitable connections.

\Vhile I have shown the vertical walls 5 and the hopper portion 6 of the ash pan as being made in one piece, it is obvious that they can be made in separate pieces and connected together. r

The virtue of spacing the inclined walls of the ash pan over the mud ring resides in the ability of the fireman to flush these walls with a hose to clean the same-from ashes when the engine is spotted, that is, in the roundhouse or over a pit.

It will be readily understood that minor changes ,in the size, form and construction ofthe various parts of my improved locomotive ashpan may be made and substituted fol-those herein shown and described, w1thout departing from the spirit of my invention, the scope of which is set forth in the appended claim.

I claim:

A locomotive ash pan comprising inclined members spaced from the mud ring of the boiler, said members having flanges at their lnner edges to wlnch 1s secured a troughshaped bottom member comprising a curled se mental' element termin an inclined curved bottom wall of variable depth which is open at its deepest end, in combination with-a door for closing said opening, and means for operating said door.

In testimony whereof I hereunto ailix my signature in the presence of two witnesses, this fifth day of December, 1917.
